IMPROVED NUTMBG-GRATBR.

TO ALL WHOM IT MAY GONCERN:

Be it known that I, CHARLES A. DURGIN, of the city, county, and State of New York, have invented a new and improved Grater; and I do hereby declare the following to be a full, clear, and exact description tliereot', reference being had to the vaceompanying drawings, figures, and letters of reference thereon, making part oi' this specification. Of the said drawings- Figure I is a perspective view; and

Figure 2, a transverse section of said gruter.

Similar letters of reference indicate like parts on all the drawings. Y l

In the use of convex graters, at present used for domestic and other purposes, the hands of the operator are often injured by coming in contact with the roughened surface, while the article or `substance being reduced will slip about onthe convex surface unless held with considerable force thereto.

My invention completely obviates these objections, and consists in the employment and use of rougliened grooves or furr'ows, in which the article to be grated is moved to und fro.

To enable others skilled in the art to make and use my invention, I will describe the construction and use thereof. i 4

To a metal plate, A, is secured, by solderingor a rim turned down, a metal plate, B, provided with one or more roughened grooves b, the ridges or projections a. being left smooth over and along which the fingers of the operator glide while the material is being grated. It will be obvious that a grater thus made will reduce the substance to be grated much faster than a convex grater, as a larger surface of the substance is acted upon. The roughened grooves b being of a size to correspond, or nearly so, with the size of the article to be reduced, may be of different sizes upon the same plate, for larger or smaller articles. v

Having thus fullr described my invention, I claim as a new article of manufacture a grooved or concave grater, substantially us described and specified.

C'. A. DURGIN.
